Hi Jack,
I think a road block for getting this started would be not knowing how your product connects or functions. While we could build a terrain and Thunderbolt model, it doesn’t mean that your track can function on it.
Were you looking for members to be compensated for their time or just be motivated by their own interest? It’s great of you to offer to cover material costs, but I just wanted to make sure everyone was on the same page with expectations.
